IMPROVEMENT 1N LocomorlvE HEAD-LIGHTS.

Specification forming part of Letters Patent No. lfg, dated February l0,1874 application filed October 20, 1873.

To all whom it may concern:

Be it known that I, THOMAS S. RAY, of Butla falo, inthe county of Erieand State of New York, have invented a new and useful Improvenient inLocomotive Head-Light Burners, of which the following is aspecification:

This invention relates to that kind of locomotive head-light burners inwhich the ordinary annular wick-tube is encircled by a verticalair-tube, to direct vertically-ascending currents of air to the outsideof the annular flame, the upper end of such tube being en larged, andperforated for the entrance of air laterally. My improvement consists inelongating the exterior air-tube so that its lower end shall reachthrough the reflector, to prevent any drippiugs or overiiow of oil frombeing spattered, by the vibrations of the burner when the locomotive isin mot-ion, upon its reflecting-surface, and injuriously affecting itspower.

Figure l is an axial section of my improved burner, showing also aportion of the reflector of a locomotive head-light. Fig. 2 is asectional elevat-ion. Fig. 3 is a transverse horizontal section.

The same letters of reference are used in all the figures in thedesignation of identical parts.

The wick-tube consist-s, as usual, of two concentric cylinders, H andH', between which the annular wick is inserted, which is raised andlowered through the medium of the ring I,- rack K, pinion L, and shaftL1 L2. Air is supplied to the interior surface of the annular iiamehrough the open-ended cylinder H of the wick-tube; and the air for theexterior surface of the iiame is drawn through the tube A encircling thewicletube, the air entering at its 4lower open end, aswell as throughthe perforations Fin the wall of its upper end B, which is suitablyenlarged to increase the aggregate area of the perforations F. ln theexample illustrated, the end B is made separate from and slipped uponthe main part of the tube A, and terminates on top in a chimney-galleryand the deflector D, which is perforated, as usual, at` G. The button M,above the deiiector, is supported upon a central stem risin from theinterior cylinder I-I of the wick-tube. The air-tubeAis sufficientlyelongated to reach, when the burner is properly attached to theoil-reservoir, through the reflector N, and thus prevents the spatteringof drippings upon its reiiecting-surface. The tube A is made as Small aspossible, so that but a slightly larger opening needs to be cut in thereflector than ordinarily; and, on account of this contracted nature ofits main body, the enlargement of its upper end becomes very important,in providing the means for supplying the required amount of air to theouter surfaceof the iiame.

`What I claim as my. invention, and desire to secure by Letters Patent,is-

lhe annular wick-tube, in combination with an encircling air-tube, A,provided with an eularged perforated upper end, B F, and with its lowerend extended downward through the reflector, substantially as and forthe purposes
